. SPECIFICATION forming part of Letters Patent No. 734,238, dated July 21 190B. Application filed May 27,1902. Serial No. 109,246. (No modelJ To al?, whom, it may concern:

Be it known that I, AUGUSTUS W. OTTIG- NON, a citizen.of the United States of America, and a resident of the city of Seattle, in

the county of King and State of Washington,

have invented certain new and useful 1mprovements in Depurators, of which the following isa specification.

My invention relates to improvements in 1o depurators, and has special reference to an apparatus of this nature which is convertible for either topical or general use.

Among numerous objects attained by this invention and'readily understood from the x5 following specification and accompanying drawings, included as a part thereof, is the production of a simplified and inexpensive depurator embodying essential features of adjustment and adaptability which render it 2o readily convertible for use either as a cupping device or developer.

The above-mentioned and other objects equally as desirable are attained by the constructions, combinations, and arrangements z 5 of parts as disclosed on the drawings, set

forth in the specificatiomand succinctlypointed out in the appended claims.

With reference to the drawings filed herewith and bearing similar reference characgo ters for corresponding parts throughout, Figure 1 is a perspective view of my improved depuratorvas arranged for use as a developer and indicates at the side one of the-short fender-bolts used to secure the cup when the device is converted for cupping. Fig. 2 is a longitudinal diametrical section of same with the elastic diaphragm removed. Fig. 3 is a diametrical section, on large scale, of the removable cap, indicating the preferred man- 4o ner of forming the valve-seat. Fig. 4 is a plan view of the center portion of said cap, disclosing said seat with the valve removed. Fig. 5 is a perspective View of the coupler preferably employed between the sections of the depurator to facilitate the connection thereof. Fig. 6 is a diametrical section of the elastic diaphragm, and Fig. 7 is a similar section of the apparatus as converted for use as a cupping device. 5o This apparatus includes a longitudinally extensible and contractible vacuum-chamber 10, embodied in a tubular cylindrical column, as l0', preferably composed of a metallic base or cup section 12 and a removable section 14, adapted to extend the column and preferably composed of transparent material, as glass, a removable organ-receiving diaphragm 9, and a suitable removable cap 16, adapted to iit the top end of either section comprising said chamber. This cap is removably fixed in such positions by suitable bolts, as 18 and 18',v the former being rendered of proper length to engage the base 12 and cap when the sections are kcombined to extend-the chamber 10 for use as a developer for topical use and the latter of suitable length to likewise engage the base and cap when the extension-section is removed to contract the chamber 10 and convert the apparatus into a cupping device for general use.

In the present embodiment the bolts 18 and 18' are rendered of identical shape and are made, preferably, with hook-heads 19, adapt'- ed to engage a suitable shoulder 2O on the base part and which consists of a peripheral flange disposed substantially midway the height of the base and having the lower surface undercut t0 offer more secure engagement for the bolt-heads and preferably eX- tended-entirely about the base to facilitate setting of the bolts. These bolts have screwthreads on the outer ends, by which clamping-nuts, as 21, can be brought to bear upon the top surface of suitable ears 22, secured on the periphery of cap 16 and arranged with U-shaped notches in the outer ends to receive the bolts, and thereby facilitate their placement and removal.

As now considered, cap 16 is rendered of suitable plate metal and is made with an outer and inner depending annular flange 15 and 17, adapted to form therebetween a seat for an annular gasket, as 23, by which the joint between the cap and either section 12 or 111 is packed and whereby it can be hermetically sealed by action of the clampingnuts 2l. This cap is also provided with a centrally-located valve-seat 24, preferably formed integral therewith and disposed in the base of a' nipple-seat 25, arranged on the cap for the attachment of a suitable air-exhausting apparatus, whereby a vacuum is created in the UNITED STATES 'PATENT w IOO depurator and a screw-threaded vent-aper ture S normally closed by a thumb-screw 31, by the removal of which the vacuum may be dispelled, as desired.

The valve-seat 24 is preferably made by first drilling a duct, as 26, and then forming a concave 27 in the metal at the base of the bore of the nipple-seat concentric with said duct and of suitable size and shape to receive loosely a ball-valve 29, which is then inserted, and portions of the metal of the wall of said bore just above the ball are upset at diametri@- ally opposite points by gouging into the metal to force portions thereof, as 30, at separated points into the path of outward and opening movement of the ball, and thereby insure it from displacement orloss in a most inexpensive manner and at the same time afford airexhaust passages between these upset portions.

Reference character 32 indicates a coupling-ring employed to facilitate connection of the base-section and extension-section and comprising an annulus having a plurality of lugs 34 arranged on each side face at the periphery and of suitable height to securely retain packing-gaskets, as 35, at each face and to embrace the abutting ends of the sections -forming the chamber 10. This coupler preferably consists of a single piece of pliable plate metal rst formed with six lugs 34, radiating from the annulus and then completed by bending alternate lugs in opposite directions and substantially at right angles to a respective face of the annulus.

The base or cup section 12 is preferably formed slightly conical and rendered with a suitable peripheral tiange, as 37, at the lower end, which is outwardly and upwardly curved as viewed in cross-section, so as to provide a smooth bearing-surface to facilitate sliding the apparatus over the surface of the body when operating as a cupping device and to also form a suitable peripheral rim by which the diaphragm 9 is conveniently removably attached when the apparatus is converted for operation as a developer. The diaphragm 9 comprises a tubular section of suitable elas` tic material, as rubber, conveniently rendered slightly conical, so that the upper end will forcibly embrace the aected organ, and formed with an outwardly and upwardly curving rim 38 at the base adapted to ex pand sufficiently to receive the flange 37 and be thereby conveniently attached for ready disconnection of the chamber l0 therefrom if desired to leave the diaphragm in place on the olgan as a spermatic ring.

A depurator constructed substantially as heretofore set forth is readily adjusted to render the vacuum-chamber of propel-size for ilse as adeveloper or cupping device and may be expeditiously converted from one to the other. Furthermore, it can be separated for replacement of broken or Worn out parts, and also after being used as a developer,

when the parts can then be readily and thoroughly cleaned.

When desired to employ the apparatus as a developer, it is assembled in extended form with the diaphragm 9 attached, when it is placed over the organ in the ordinary manner and the air then exhausted as desired, and, if desired, the chamber may be readily disconnected from the diaphragm as the apparatus rests in place by simply stretching the rim 3S from the flange 37, thus leaving the diaphragm on the organ to act as spermatic ring. If it is desired to employ the apparatus as a cupping device, the extensionsection, cap, and diaphragm are removed and the cap replaced on the base-section, when the vacuum-chamber will be of proper length for more perfect application as a cupping device and the apparatus can be more readily and expeditiously handled and employed in the well-known manner for general applications.
